I repeat: like TiVo for radio. Not only does Radioshift record streaming audio in all popular formats — RealAudio, Windows Media, QuickTime, even AM/FM if you have a Griffin Radio Shark — but it also offers 50,000 schedules for programs and radio stations, so, like with TiVo, you can simply subscribe to the shows you want to follow and they’ll be recorded automatically. But unlike TiVo, the programming schedules are free — you pay $32 for Radioshift and the program schedules are just there.
